However, given the fact that this number measures "pages", the PAGE_SIZE on Ultra/Alpha, and the size of the 64-bit user address space on Ultra and Alpha, it would actually end up working. This doesn't make it a good idea though. Later, David S. Miller davem@redhat.com -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
